Work: Calculate the value of equation 0.3*55.2*2+18.9*0.3*2+7.95*0.2*13+39.2*0.2*2 .
Question type: Mathematical calculation
Solution:
0.3*55.2*2+18.9*0.3*2+7.95*0.2*13+39.2*0.2*2
=16.56*2+18.9*0.3*2+7.95*0.2*13+39.2*0.2*2
=33.12+18.9*0.3*2+7.95*0.2*13+39.2*0.2*2
=33.12+5.67*2+7.95*0.2*13+39.2*0.2*2
=33.12+11.34+7.95*0.2*13+39.2*0.2*2
=33.12+11.34+1.59*13+39.2*0.2*2
=33.12+11.34+20.67+39.2*0.2*2
=33.12+11.34+20.67+7.84*2
=33.12+11.34+20.67+15.68
=44.46+20.67+15.68
=65.13+15.68
=80.81
Answer:0.3*55.2*2+18.9*0.3*2+7.95*0.2*13+39.2*0.2*2=80.81
